To all whom it may concern:

Be it known that I, THEODORE N. Jones, a citizen of the United States, residing at Boulder, county of Boulder, and State of Colorado, have invented certain new and useful Im )rovcmcnts in Means for Controlling the 1 assa 'e of Explosive Mixtures to the Engine-Cylinders; and I do declare the following to be a full, clear, and exact dc.- scription of the invention, such. as w11l enable others skilled in the art to whiehit appertains to make and use the same, reference being had to the accompanying drawings, and to the letters andfi arcs of reference marked thereon, which orm apart of this specification. t

My invention relates to improvements in means for controlling the passage of explosive mixture to the cylinders ofinternal combustion engines my special object bein to make it practicab explosive mixture to the cylinders and-lock the controlling mechanism in this positionv to prevent aaunauthorized person from.op-' crating an automobileequipped with an engine of this character.

"he mechanism is so arranged that the passage leading from the carbureter to the engine cylinders may be closed when the owner leaves the machine. The construction is of such character that only the owner or an authorized person who understands the lock construction will be able to manipulate it for the purpose of opening said pas sage. I In my present improvement I employ a combination lock construction whose. tumblers are adapted to be manipulated by means of rotary tubes arranged one within the other and conveniently accessible to the ehautl'eur, or person in charge ofthe machine. Having briefly outlined my .improved cmistruction, I willproceed to .describethe same in detail, reference bein madetothe accompanym draw ng in ,w 1ch\1s 1l lustrated an em od1ment t ereoii;

"The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate an explosive engineand 6 the main. pipe leadin from the earbureter, and 7, branch pipes ending to the respective'cylinders of the engine.

; The'main pipe 6 is interrupted by a casing 8 which cuts the same intermediate its extremities,-and is in communication there .with., As'shown in the drawin this casing is into ral' 'with the pipe. Wit iin this casing is ocated a core 9 which is disposed longitudlnally of the casin and'having its axis coincident therewit One extremity 10 of this core is threaded into a socket 12 formed in the outer extremity 13 of the easing. This core extends forwardly within the casing and is provided with a tongue 14 exteriorlv located-thereon and extending longitudinally thereof. This tongue occupies,the;'highest position on the core, or is uppermostwhen the device is in use. Furtongue' 14- is in alinement longitudinally wit a mark 15 formed on the dash-board ltl directly in front of the driver of the mach1ne.-

The casing has front and rear projections 17 and 18 respectively from the pipe 6, and a'tube 19 is fitted into the casing and adapted, when at its forward limit of movement, to cut off-communication between thecarbu- 'reter .20'andthe engine. In order that a fiuid-tight'joint may be formed around the .tubet-lQ/when it ientersthe open rear ex- LployedqThetube 19.fits closely within the'jcasmg, but is rotatably mounted, for a purposey ereinafter?explained.- A second tubej-22 is=intro ducedy-into the tube 19 from the" rear and journaled therein at its outer .tremityt-ofi.theorising, a stutiing-box 21 is thermore, the core is so arranged that the ment'witha mark 30 formed on the for extremity, asfshown at 23, its inner extrein "lty b'eingconnected with a tumbler of the lock, as hereinafter explained.

Within the forward extremity ofthe tube 19 a tumbler 24 is located, said tumbler eon sistmg of a body member 25 and a ring 26, the two parts being connected by a screw n The tumbler is connected withthe forward'extremityof the tube by means of a pm 28 which" passes through a slot. 29

formed in the forward "extremityf'of the tube. This pin may be arranged in'alineward extremity -of the tube, and thc pin may also.be diametrically arranged'wvith reference to a slot. i-ll formed in the member 95 of 'lhe tumbler, 'and'of such-size as to a receive theltongue 14 of the core when the jcctions 82 on the-forward portion thereofl spacing--- the tumblers tumbler is so arranged :that the slot, or gl'oove,'l$ in alinement with the saidtongue.

In order to make' provision' for properly and maintaining them, in propcr longitudinal position within the tub'e, an d at th e same time'permit'them ,to be rotated within the tube and upon the core, the tongue 1 4 is recessed tojform "pro the saitlpi'ojectioiis being in alinement with fromuthe -cngine.'-"

This click-ball 36 is yieldingly held in engagementwith one of 'the'grooves 38 of the 1 core, the said grooves.- being so constructed .as to allow'a segment of the'ball to enter, whereby each tumbler its-temporarily locked in any desired positionofv rotary ad justment upon the" corem. l urthcrmore; every time a tumbler is adjusted rotatably and moved a space equal to that between'thegrooves 38 of the core, the ball is suddenly forced into a groove which it enters with aclick, thus notifying the person in charge of the mechanism that the tumbler has traveled a single rotarystep in its movement ion the COI'C. i

prbjcction,.43,'formed on a ring 44 constituting a' member of another tumbler 45, the .ringit being connected with the body member 46 of this tumbler by means of a screw 47? This is important, since the second tum- ,bler.v is manipulated to bring its slot 49 into alinement with the tongue 14, as hereinafter explained.

- Itrmay be assumed that the two-tumbler members 25 and 26 are so arranged that the. stop 41 in the groove 42 located in longitudinal alinement with reference to the slot ill uiulon the same side of the core, and that .theprojee tion 43 of the tumbler member ll "pf effecting a longitudinal adjustment of 'the tubill) to bring it into position to open the passage to the part 6 to allow the explosive mixture to flow to the engine, mustunderstandthe relation of the position of the-mark 80ft0 that of the slot 31, and, as

it ha's already been explained that the pin feoiinecting the tumbler 24 with the tube is inllongitildinal alinement with the mark 30 and-that the slot 31, when the tumbler is inserted in the tube, is diametrically arranged with reference to the pin 28, it will be understood that the tube 19 must be given a half turn fromthe position shown in Fig. 1

in order to bringtheslot 31 into alinement *withtheftonguc 14, the latter being uppermost on the core and inalinement with the mark 'llron the dashboard. It is also assumed that the tube 19 is in such position that" the mark 30 is in alinement with and a djacent'to the mark 15. As the core 9 has -ten-grooves 38, the operator will know that ifhetiirns' the tube 19 five steps, or a sulli- .cient distance to produce five clicks, the slot. :31 of. the tumbler 2-1 will be in position in alinement 'with'the tongue 1-1 and in position to slide"longitudinally on the tongue, since the slots of all the tun'iblers are of such s ze as to'allow the tumblers to move longitudinally, on the core when properly adusted. As soon as the tumbler 24 is in this position, thestop '41'i carricdthercby will be f'in 'engagement. with-the stop 43 carried. by he,,Ir lember,f1-.4:of the. tumbler 4-5 and-by tuei ofthe'relativeposition 'ofthe stop 43 Jit'willf'be' necessary to continue the rotation jQ =the-t-ubeilll and thetumblcr. 24 another elf'turni.orLfive-bllblts, inorder tobring the o 519 'nt'o"alinementi withthe-tongue 14 Ill on the same side of the structure, and when this is accomplished the slot 31 of the tumbler 2-1 would necessarily be in its original position, or on the opposite side of the core from the tongue 14. Hence, a half revolution of the tube 19 in the reverse direction will bring the slot 31 into alinement with the slot 49, both slots being in alinement with the tongue 14 and on the uppermost side of the structure. The two tumblers 24 19 to move longitudinally with reference to the core, but. the two other tumblers, which I will designate by the numerals and 51, must also he mani ulated in a manner that will now be descri led.

lhe inner extremity of the tube 22 is connected with the tumbler 50 by means of a pin 52, the said pin entering the member 53 of the tumbler, the latter being connected with the member 54 by means of a screw 5."), or other suitable connection. This tumbler 5O carries-a ball 56, a spring 57, the said spring causing the ball to successively enter the grooves 38 during the rotation of the. tumbler upon the core, the outer extremity of the spring 57 engaging a plug 58. This tumbler 50 is adjacent a tumbler 51 composed of two members 60 and 61, connected by a screw 62, the said tumbler 51 carrying a ball 63 actuated by a spring 64 engaging the ball at one extremity and a plu 65 at the opposite extremity. The tum ler 50 carries a stop 66 which extends into a groove 67 formed in the tumbler 51, and the last-named tumbler is provided with a stop 68 also located in the said groove and in the path of the stop 66. \Ve maynow assume that the two slots 69 and 70 of the tumblers 50 and 51 are in alinement with each other, and diametrically arranged with reference to the tongue 14 of the core. -It will also be assumed that the in 52 which connects the tumbler 50 with tie tube 22 is diametrically located with reference to the slot (39 of the tumbler, the said pin being in nlincment with a mark 71 on the rear exposed extremity of the tube 22. A person, in order to manipulate the lock, must be in possession of this information. He will then turn the tube 22 a half revolution, pro dueing five clicks of the ball 56. This will bring the slot (3!) into alinement with the tongue 14 of the core, and also with the slots 31 and 45) of the two tumblers 24 and 45. A t the same time the stop 66 will be brought into engagement. with the stop (38 of the tumblerfil, and as the rotation is continued another half turn, the slot. 70 of the tumbler 51 will be brought into alinement with the. tongue 14-, and on the upper side of the mechanism. Then by turning the tube 22 a half revolution in the reverse direction the slot 69 of the tumbler 50 will be again brought into alinement with the tongue 14 and inthe uppermost positions Hence all of the tumblers will now have their respective slots in alinement with the tongue 11, and the operator, by pulling reanvardly upon the rear extremity of the tube 22, will move both tubes rearwardly and change the cut-ofi' position of the tube 19,sec Fig. 2. The explosive mixture can then flow readily to the engine in the usual way. Then, however, it is desired to stop and leave the engine, the tubes will be again returned to the )osit-ion shown in Fig. 1, and so manipuated as to throw oil the combination in which event no one will be able to open the passage through the pipe (3 to allow the explosive mixture to [low to the engine except; the person who knows the combination of the lock mechanism.

It is evident that \vhcn the combination is thrown oil", the two tubes 19 and may be in any desired relative positions. The operator, however, in order to unlock the structure, will first turn the tubes into position to bring their marks 71 and 30 into alinc' ment with the mark 15 of a dash-board. He will then know that he must. give each tube a complete rotation in one direction, and a half rotation in the reverse direction, in \order to be able to move the tubes longitudinally upon the core whereby the passa e through the pipe 6 may be unobstructed. lt;

is evident that any other desired arrangement or combination may be obtained by changing the relative positions of the mem bers of the various tumblers. For instance, instead of connecting the two tumbler members 25 and 26 in such a manner that the stop 41 will be diametrically arranged with reference to the stop 43 of the tumbler 45, the stop 41 may be so arranged that only two clicks will be necessary during the manipulation of the tumbler 24 to bring the stop 41 into engagement with the stop 18. Then it will be necessary to turn the tumbler 21 five clicks in order to bring the slot 49 into alincment with the ton no 14 on the same side of the structure. '1 ion a reverse. movement of two clicks only will be necessary to bring the slot 31 into alinemcnt with the tongue 14 on the same side of the structure. In this way, it will be understood that a great variety of combinations may be obtained, and that any combination may be made as complicated as may be desired.

As illustrated in the drawing, the inner tube 22 is provided with a collar 72 adapted to engage a shoulder 73 formed on the outer tube 1!), whereby the. rearward movement of the ripe 22 will carry the pipe 19 therewith, while the forward ll'lOVOlllOlll} of the tube 22 will, by its pressure on the tumbler 4G, carry the tube It) forwardly, since the tumbler mechanism is closely interposed between the .forward extremity of the. tube 22 and an interior collar 74 threaded into the forward extremity of the tube 19, this ring 74 being &

introduced after the tumbler mechanism is in )lace.

1; should be understood that one tumbler member of each tumbler is provided with a series of threaded recesses 75, while its companion member is provided with a sin 'le recess 76, whereby a screw inserted in the last-named recess may enter any one of the recesses of the companion tumbler member, thus making it practicable to change the relative positions of the stop 41, for instance, of one tumbler member with reference to the slot 31 of its companion member, and whereby the relative position of the stop 41, for instance, of one tumbler member, may be varied with reference to the stop 4-3, for instance, of an adjacent tumbler.

The outer exposed extremities of the tubes 19 and 22 may be provided with marks 77 corresponding in number with the grooves 38 of the core, and correspondingly numbered,see Fig. 3. This, however, is not necessary, since the clicks incident to the engagement of the balls with the grooves of the core as the tumblers are manipulated, will enable the operator to know the exact distance traveled by either tube in a rotary direction, since ten clicks indicate a complete revolution. The outer extremities of the two tubes are milled, as shown at 78 and 79, to facilitate their manipulation. It will be understood that the two tubes 19 and 22 are concentrically arranged, whereby their axes are coincident.

In order to limit the upward movement of the tube structure to a position when it has been withdrawn far enough to completely open the passage-way through the conduit (3, the outer tube 19 is equip ed with a stop-collar 80 which, when the tu ular construction has been withdrawn to the position shown in Fig. 2, will engage a shoulder 81 mounted on the dash-board of the machine. This makes it practicable for the person in charge of the machine to open the tube 6 for the passage of explosive mixture, to its full capacity, without exercising any special care, since he is only required to draw outwardly on the tube structure until the stop-collar 80 engages the said shoulder.

Attention is called to the fact that the pin 28 which connects the tumbler 24 with the operating tube 19, enters the ring member 26 of the tumbler 24, since this ring member may always maintain a predetermined relation with the slot 29 of the said tube. It is important that this pin be connected with the ring member 26 rather than the body member 25 of the tumbler. since in changing the combination the relative po sition of the member 25 within the tube will vary as the combination is changed, and it is desirable that the )in 28 should remain fixed within the tumbler. Both of the pins 28 and 52, by virtue of the fact that they enter the ring members of the tumblers, may remain fixed within their tumbler members regardless of the relative change which takes place between the body members of the tumblers and the tubes within which they are located. As these pins engage slots which are open at the rear ex trcmities of the tubes when the latter are removed from the casing for the purpose of changing the combination, the tumbler structure may be disengaged from the tubes at their rear extremities when the interior collar T-i is removed from the tube It). Attention is also called to the fact that the stop-collar 80 is adjustable on the tube 19, since by removing its fastening screw 82, it may be moved toward the rear extremity of the tube 19 as the latter is withdrawn from the casing, thus making it practicable to completely remove both tubes from the machine when, for any reason, it may be de' sirable, as for the pm 3052 of changing the combination of the look. It will be understood that when thcse tubes are removed the core 9 will remain fixed within the casing, and the tumbler construction may be readily withdrawn from the rear extremities of the tubes, and adjusted for the purpose of changing the combination, as will be readily understood.
